I have a 1988 Cobra 4.3L engines and have been beating my head trying to resolve some engine issues. The engine when running seems to have a miss and loss of power. It appears to have no fuel issues and actually replaced the carb today. At both idle and attempting running speeds I have had several people including myself hear this miss. After being on the water last weekend when I came back in we pulled the plugs thinking one might be fouled but they all looked good and by the way were all replaced this spring along with cap and rotor. Another reason was the boat seemed to run real rich cause you could smell the fuel. Looking at the carb and its conditioned I just went ahead and decided to replace since it looked original and thinking that would help with the hard start and idling issues.
After replacing the carb the boat fired up without having to choke it and was still hearing the miss. Took it out and it still has a loss of power getting on plane and the miss is there thru all acceleration speeds.
Came back in again pulling plugs which looked fine and checked all the wires to make sure I didn't accidentally criss them earlier this year when I changed the cap. Also why checking the wires we actually pulled a few off the cap and there was absolutely no change in the way the engine was running. My brother in law suggested trying new wires but I read somewhere that those should not have to ever be replaced.
Truthfully at this point myself and others are sure what to check or where to go next. Any suggestions would be appreciated if we might be overlooking something. Naturally like all I am trying to avoid the high cost of a service shop but to the point of dropping it off and saying do what needs to be done. I guess that's part of the frustration of not being able to use it. Any assistance or suggestions would be appreciated.
